The Maclaughlin River, a perennial river of the Snowy River catchment, is located in the Monaro region of New South Wales, Australia.
The Maclaughlin River rises on the southern slopes of the Great Dividing Range approximately south southeast of Nimmitabel. The river flows generally west and then southwest, joined by two minor tributaries, before reaching its confluence with the Snowy River approximately south by west of Mount Rix. The river descends over its course, flowing through Merriangaah Nature Reserve.[1]
In its upper reaches, the Maclaughlin River is crossed by the Monaro Highway near Nimmitabel.[1]
